Volcanic ash detector to safeguard air travel

Australia’s Commonwealth, Scientific and Industrial Research Organisation (CSIRO) and Tenix have developed an airborne volcanic gas and ash detector that could improve safety for air travellers.

Air safety will be boosted and the world aviation industry is set to save millions of dollars with the development by Australian company Tenix and CSIRO of an airborne volcanic gas and ash detector.

Costs in excess of $250 million have been borne by airlines worldwide as a result of undetected volcanic ash in flightpaths. Silicate particles in the ash can enter the engines and melt, leading to serious engine damage.

Volcanic ash also causes windscreen scouring, instrument damage and even complete loss of power on jet airliners.

The CSIRO-developed Ground-based Infra-Red Detection (G-bIRD) system has been designed for installation in areas where hazardous volcanic gas and ash clouds may be present, including the heavily-travelled routes across the North and South Pacific.

Tenix successfully tested the device in Hawaii and Guam earlier this year, and at the base of Mount Etna in Sicily last month. The trials are part of Tenix’s work with commercial and government partners to make G-bIRD available at cities and airports near volcanoes, to provide early warning and data about the nature and location of ash and sulphur dioxide clouds.

Tenix Group Managing Director Paul Salteri said today that an average of at least one volcano erupted somewhere around the world each week, causing regular hazard to airline traffic.

‘G-bIRD has the potential to become an integral part of air transport safety systems and further reduce the risks of air travel,’ Mr Salteri said.

The technology was developed in Australia in the 1990s by CSIRO Atmospheric Research scientists headed by Dr Fred Prata. Tenix joined the multimillion-dollar development 12 months ago and is responsible for the detector’s commercialisation.

The technology may also be used for environmental monitoring of sulphur dioxide and sulphuric acid (acid rain) clouds to assist people suffering from asthma and other respiratory diseases.

Tenix’s work on G-bIRD is part of its A$40 million Take to Market Investment fund, involving projects requiring a mix of capital and commercial input.
